Masoneilan 49000 Series

V-LOG™ Low-Noise Anti-Cavitation Valve

The 49000 Series V-LOG high pressure drop valve features an enlarged body gallery to accommodate gas expansion and up to 36 stages of pressure reduction via a stacked disk trim design. It offers optimized severe service solutions for high-pressure drop applications with potential damaging noise or cavitating fluid conditions. Built around the Masoneilan V-LOG Energy Management Trim, the 49000 Series is capable of handling a wide range of both liquid and gas services in a variety of process industries.

Benefits of the 49000 Series V-LOG high pressure drop valve include:

Compared to forged or fabricated bodies, the cast globe-style body of the 49000 Series offers lower in weight and overall dimensions which helps reduce installation costs.
Enlarged body galleries and expanded outlets provide velocity control for expanding gases.
Galleries sized to accept "typical" V-LOG trim dimensions for a standardized body platform and an optimized solution.
V-LOG trim for use with either compressible or incompressible fluids under severe service conditions.
V-LOG and Lo-dB trim provide reduced noise and cavitation that could negatively affect the valve and/or surrounding equipment.

The V-LOG Trim

can be configured for use with either compressible or incompressible fluids under severe service conditions making the 49000 Series valve a superior choice for liquid and gas applications including:

Boiler feed water start-up and control
Steam letdown
Pump discharge
Water reinjection
Gas recycle
